Merge separated illustrator path points

We were trying to export some 3d Drawings from Solidwords to eps file for the old router machine to cut. To do that we have to first export as dwg. In the dwg file our paths we all broken. We had group them together to allow the router to cut properly.

To do that first select all the lines that you need then open Pathfinder and use the ” divide ” feature and it will merge. I don’t understand how this works as the name is the opposite of what we are trying to do. but it works 😀 hope this helps someone.
